Answer:
B Structure :)
Explanation:
Not every evosystem has large areas of similar vegetation, as the habitats in you study do. I'm areas where patches of more visually varied habitats exist, individual snails regularly move into or out of different visual surroubdings
Answer:
High diversity of organisms are present.
Explanation:
Due to the existence of varied habitats in the ecosystem, there is high diversity of organisms in that ecosystem because there are different types of habitats are present in that ecosystem. Due to presence of more habitats for organisms and suitable conditions, different types of organisms lives in that one ecosystem which increases the diversity of that ecosystem. If the ecosystem has only one type of habitat, then the ecosystem will be less diversified as compared to ecosystem having varied habitats.

Scientists have recorded increasing ocean temperatures. Which of the following is not a consequence of these increasing global temperatures?
altered species interactions
lower salinity in ocean water
shifts in the range of habitat for organisms
changes in the seasonal abundance of populations
Answer:
Lower Salinity in the ocean water.
Explanation:
The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
As temperature increases, the space between water molecules increases—also known as density, which therefore decreases. ... Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases

Think about a model that you can construct that could be used to show the difference in prokaryotic and eukaryotic cells. In 6 complete sentences(3 for each type of cell), explain the process you would use to construct the model and how you would use the model to explain the differences between prokaryotic and eukaryotic cells to your classmates.
Answer:
Prokaryotic cell-- no organelles, no membrane.
Eukaryotic cell -- Have organelles and membrane.
Explanation:
For the model of prokaryotic cell, we construct the model by removing organelles from the cell whereas in the eukaryotic cell, we add the organelles because in eukaryotic organisms, organelles are present in the cell that performs specific function. In the model of prokaryotic cell, we have to remove membrane around the nucleus whereas membrane president around the nucleus. In the prokaryotic cell, nucleus is not visible while on the other hand, in eukaryotic cell, the nucleus is visible and can be differentiate from other organelles.

Which description explains why there are two high and two low tides in a day? (4 points)
Earth moves closer to the sun and moon twice a day.
Earth revolves around the tidal bulges created by gravitational forces.
Earth rotates in and out of a tidal bulge twice a day.
The moon's gravity increases over the oceans and decreases over the land.
Answer:
Earth rotates in and out of a tidal bulge twice a day.
Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.
The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.

What happens when you combine two clear liquid solutions, a thick black solid material forms on the bottom of the beaker.
Answer:
See explanation
Explanation:
A precipitate is formed when a mixture of two soluble substances results in the formation of an insoluble product. It usually happens during a double decomposition reaction.
The two clear liquids combined both contain soluble substances. These interact to yield an insoluble product also known as a precipitate which is black in colour and settles on the bottom of the beaker.

Base your answer to this question on the following information: You have isolated a primary signal factor from the blood of a space alien, which you name XFF (for X-files factor). You also have Isolated various types of alien cells which appear to Interact with XFF. Based on preliminar data, you think that XFF could be similar to one of three compounds normally found in human blood: epidermal growth factor (EGF), epinephrine, or estrogen. Which of the following would best be used to demorstrate XFF is most like EGF?
A. exposure of cells to tyrosine kinase inhibitors
B. microinjection into cells of nonhydrolyzable GTP analogues
C. exposure of cells to ryanodine
D. exposure of cells to radioactive XFF
E. receptor binding assays
Answer:
The correct answer is - A. exposure of cells to tyrosine kinase inhibitors.
Explanation:
EGF or epidermal growth factor is a protein compound found in human blood responsible for signaling is the member receptor tyrosine kinase family of proteins.
EGF signaling leads to activation or stimulation of various pathways such as Phosphatidylinositol 3-kinase, Ras and or Raf signaling, and or Akt signaling chain of reactions, or STAT pathway. By exposing the cells to the tyrosine kinase inhibitors leads to any of the given pathways then XFF is most likely similar to EGF.

Describe an experiment used to prove that amino acids and sucrose go up and down the phloem.
Answer:
By using carbon-14 in the experiment in order to prove the statement.
Explanation:
Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.

what do we call the actual gas or substance that causes air pollution?
Answer:
The actual gas that causes air pollution is called a pollutant
Explanation:
Air pollution is the decrease in air quality. Air pollutants are the gases that cause air pollution.
What are pollutants?Pollutants are harmful substances and particles that affect the quality of the environment and are man-made or natural. Fly ash from volcanic eruptions is a natural pollutant that deters the air quality.
The air pollutants like carbon monoxide, sulfur dioxide, and carbon dioxide released from the burning of fossil, coal, and vehicles alter the air quality and result in a change in weather conditions.
Therefore, the pollutants are the actual gases that cause air pollution.

Cory states the following argument about the evolution of aardvarks and anteaters.
"Aardvarks and anteaters both use long, sticky tongues to capture and eat ants or termites. Aardvarks are native to Africa, while anteaters are native to the Americas. However, their similarities provide evidence that both groups of species evolved from a common ancestor that used its tongue to eat ant-like insects."
Which claim, if supported by evidence, would provide the strongest counter-argument AGAINST Cory's argument?
A. The tongues and diet of aardvarks and anteaters are an example of convergent evolution.
B. The tongues and diet of aardvarks and anteaters are an example of adaptive radiation.
C. The Americas and Africa were once joined together, and animals roamed freely between the two lands.
D. A long, sticky tongue evolved in response to the tunneling behavior of ants, an example of coevolution.

Answer:
its d repair crlls can't repair itself
Cell division is the division of cells through a series of events. It results in reproduction, growth and repair. Nutrition is not a result of cell division.
What is a cell cycle?Cell cycle is a series of event where a cell grow, differentiate, accumulate nutrients, duplicates its genome and divide to form daughter cells.
Cell cycle has two phases in which one is interphase in which the cell grow and accumulate nutrition, along with this cell duplicates its genome. Second phase is M-phase in which cell division takes place.
Cell division helps cell in reproduction, growth and repair.
Thus, the correct option is b, as nutrition as it is not a result of cell division.

Identify the kind of response to the following argument: Argument: In nature, a species is more likely to survive when its weak members die out, so we should let the weak in our society die out. Response: In nature, a species is more likely to survive when it lives in its natural habitat, so we should live in our natural habitat. A. refutation by parallel reasoning B. refutation by reduction to absurdity C. refutation by counterexample D. not a refutation
Answer:
A. refutation by parallel reasoning
Explanation:
A refutation by parallel reasoning is an analogical inference between two arguments. This type of refutation occurs when an argument is invalidated by showing that the argument's conclusion is not supported by its premises, thereby the structure of the argument is incorrect. The parallel argument should demonstrate that the premises of the target argument are founded in a fallacy or don't provide a strong enough rationale to support/accept its conclusion.
